Senior Construction Cost Estimator
About The Position
ProSidian seeks a Senior Construction Cost Estimator to lead an independent construction cost estimate for infrastructure supporting the Electron-Ion Collider (EIC) at Brookhaven National Laboratory (BNL). The work is an Architect-Engineer (A-E) cost-estimation service supporting the U.S. Department of Energy and Brookhaven Science Associates. It covers New York State Work Package No. 02, including support buildings, foundations, electrical distribution, process cooling infrastructure, underground utilities, tunnel connections, and related site improvements. The role is remote within the United States, with on-site meetings expected and occasional travel potentially required; at least one BNL site walkdown is anticipated. The estimator will develop a detailed, defensible AACE Class 1 independent construction cost estimate to assess the accuracy, completeness, and reasonableness of projected costs before construction contracts are awarded. The work includes reviewing the 100% design package, integrating discipline takeoffs, validating labor, equipment, and vendor pricing, documenting assumptions and estimate basis, and reconciling differences with the project Architect-Engineer and BSA. The position serves as the technical lead and must maintain estimate independence from the A/E and prospective construction bidders. Deliverables include an initial estimate within four weeks of buyer input, an updated estimate after review, a final reconciliation update with detailed backup, and an Excel-compatible estimate output. The assignment is described as an anticipated 10-week fixed-price engagement. The role is contract-contingent or may be offered as a contract W-2/1099 engagement; ProSidian reserves the right to convert it to a full-time W-2 position. The posting describes the work as exempt and states there is no overtime pay. Candidates should have substantial detailed vertical or infrastructure construction estimating experience, including leadership of complex multidisciplinary estimates, experience with complete design packages and large capital projects, and third-party estimate reconciliation. A bachelor's degree in a relevant field is requested, with equivalent deep estimating experience accepted where permitted. AACE CCP or CEP is strongly recommended; PE is an advantage but not required. The posting says the precise credential and experience thresholds must be verified against the solicitation. U.S. citizenship is required; visa sponsorship is not available.
Requirements
- Bachelor’s degree in Construction Management, Civil, Mechanical, or Electrical Engineering, Quantity Surveying, or a closely related field; equivalent deep estimating experience may be accepted where permitted.
- Recommended 10–15+ years of detailed vertical or infrastructure construction cost estimating experience.
- Recommended 5+ years leading complex, multidisciplinary estimates.
- Experience with 100% design packages, AACE estimate classification, large capital projects, and third-party estimate reconciliation.
- U.S. citizenship is required.
- Ability to maintain independence from the A/E and prospective construction bidders.
- Skills in AACE Class 1 cost estimating, quantity takeoffs, CSI/MasterFormat and WBS coding, Excel or estimating software, unit-cost builds, vendor quotations, contractor indirects and allowances, labor productivity, basis-of-estimate drafting, cost indices and escalation, and cost-reconciliation analysis.
- Competencies in independent judgment, analytical rigor, traceability, professional challenge and negotiation, multidisciplinary integration, concise technical writing, quality control, and deadline management.
- Strong oral and written communication, organization, time management, prioritization, adaptability, attention to detail, and multitasking skills.
- Proficiency in project management methodologies and tools.
Nice To Haves
- AACE Certified Cost Professional (CCP) or Certified Estimating Professional (CEP) credential is strongly recommended; exact solicitation requirements should be verified.
- Professional Engineer (PE) license is an advantage but is not required.
- Experience with three relevant estimates over $75 million and a qualifying senior estimator; the exact bid qualification threshold must be confirmed in the solicitation.
Responsibilities
- Lead the independent AACE Class 1 estimate for Work Package 02 base work and add-alternates.
- Establish the work breakdown structure, estimate basis, at-year-dollar assumptions, construction cost index, escalation, and contingency.
- Review detailed engineering drawings and specifications and integrate discipline quantity takeoffs.
- Calculate and validate construction material quantities, labor rates, crew productivity, equipment costs, vendor quotations, contractor indirects, allowances, and markups.
- Develop unit-cost builds, pricing methodology, and basis-of-estimate documentation.
- Lead virtual estimate reconciliation with the project Architect-Engineer and BSA; prepare comparison spreadsheets and document quantified adjustments.
- Review and approve estimate deliverables and support a BNL site walkdown.
- Provide detailed backup and Excel-compatible estimate outputs, including initial, updated, and final reconciled estimates.
- Maintain independence from the A/E and prospective construction bidders.
- Perform quality control, data synthesis, technical evaluation, and deadline management for estimate deliverables.
